Medi-cal payment reduced to CPT® 9316 and 93018

I have billed to Medi-cal insurance with the following CPT's in hospital setting viz, 93306-26, 93016, 93018,93010-59 on same date of service for the same provider. But Medical insurance had paid only 2% of Fee schedule. Please help me out why the insurance paid only this much percentage of amount?
